The evolution of a classic.
TUNED MASS DAMPER
The two end-covers are linked by the dual avional rear wings, functioning as a high speed mechanical interface that conveys spurious vibrations to the base of the cabinet. A Tuned Mass Damper, with multiple tuning frequencies, like on record skyscrapers and F1 cars converts the residual vibrations into heat (thermkinetics) by out-of-phase vibrations.
THE ACOUSTIC ENCLOSURE
The cabinet is the highest expression of the lute shape design. The progressive gentle curve, made of multilayer cross-grained okumè, is applied through separate smoothed layers, thus applying the technique of constrained layer damping. The acoustic environment of the transducer of mid bass is optimized to a degree of theoretical perfection. Sub-structural ribs are strategically placed inside the cabinet to strengthen it. Guarneri Evolution introduces the S.M.D.: Surface Mass Damper system that minimizes any discolouring of the cabinet.
The ‘Anima Legata’, another derivative of the Sonus faber, is made up of two surfaces, worked and positioned orthogonally to a concentric compressed traction bar in the column. A thickening volumetric eliminates any resonance in the cavity of the column and thanks to the friction between the grains a thermo-kinetic dissipation is generated.
The Exo-Squeleton clamp is implemented by the 2 CNC machined avional nickel-plated end-covers (on the top and on the bottom of the cabinet). Their role is to control and constrain residual resonances of the enclosure walls. The two end-covers are linked by the dual avional rear wings, functioning as a high speed mechanical interface that conveys spurious vibrations to the base of the cabinet.
More than just a simple pedestal, the support column is a symbiotic element of Guarneri Evolution. An instrument that reflects some of the fundamental elements of the concept the Sonus faber such as L.V.T. (Low Vibration Transmission) otherwise known as a system of mechanical decoupling from the floor obtained through a specifically optimized elastomer suspension. It substantially reduces the transmission of spurious vibrations in the listening environment and inhibits the produce of damaging phenomenon such as acoustic feedback.
The Stealth Reflex is the Sonus faber patented solution to implement a para-aperiodic vented system. Besides enabling to reduce the dimensions of the cabinet, better low frequency and lower distortions are reached. It has also the advantage of eliminating the port noises typical of classic bassreflex systems.
